He told People magazine: “My mother drummed it into me to hate my father for tearing apart the family and sexually molesting my sister

“And I hated him for her for years. I see now that this was a vengeful way to pay him back for falling in love with Soon-Yi.”

Moses and Dylan, now 28, along with their brother Ronan, 26, were at the centre of a bitter custody battle in 1993 between Allen and Farrow.

Both sides testified about Allen’s affair with Farrow’s adopted daughter Soon-Yi Previn, whom Allen eventually married in 1997.

Allen, 78, has denied abusing Dylan and has maintained that Farrow, 69, coached the girl - an accusation that Farrow has always denied.

Moses, who is estranged from Farrow, but is close to Allen and Soon-Yi, said: “Of course Woody did not molest my sister. She loved him and looked forward to seeing him when he would visit.

“She never hid from him until our mother succeeded in creating the atmosphere of fear and hate towards him.

“The day in question, there were six or seven of us in the house. We were all in public rooms and no one, not my father or sister, was off in any private spaces.

“My mother was conveniently out shopping. I don’t know if my sister really believes she was molested or is trying to please her mother. Pleasing my mother was very powerful motivation because to be on her wrong side was horrible.”

Dylan insists that she is telling the truth, saying: “This is such a betrayal to me and my whole family.

“My memories are the truth and they are mine and I will live with that for the rest of my life.”

The latest revelations come as it emerged Allen has asked the New York Times to publish a direct response to Dylan’s claims.

The paper has received Allen’s response and is said to be considering the director’s request.
